  Discovery of CA-4948, an Orally Bioavailable IRAK4 Inhibitor for Treatment of Hematologic Malignancies

  摘要：

  Small molecule potent IRAK4 inhibitors from a novel bicyclic heterocycle class were designed and synthesized based on hits identified from Aurigene's compound library. The advanced lead compound, CA-4948, demonstrated good cellular activity in ABC DLBCL and AML cell lines. Inhibition of TLR signaling leading to decreased IL-6 levels was also observed in whole blood assays. CA-4948 demonstrated moderate to high selectivity in a panel of 329 kinases as well as exhibited desirable ADME and PK profiles including good oral bioavailability in mice, rat, and dog and showed >90% tumor growth inhibition in relevant tumor models with excellent correlation with in vivo PD modulation. CA-4948 was well tolerated in toxicity studies in both mouse and dog at efficacious exposure. The overall profile of CA-4948 prompted us to select it as a clinical candidate for evaluation in patients with relapsed or refractory hematologic malignancies including non-Hodgkin lymphoma and acute myeloid leukemia.

  The present disclosure relates to bifunctional compounds, which find utility as modulators of Interleukin-1 Receptor-Associated Kinase 4 (IRAK-4); the target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hppel-Lindau, cereblon, ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

  本公开涉及双功能化合物，其作为白细胞介素-1受体相关激酶4（IRAK-4；目标蛋白）的调节剂具有实用性。具体而言，本公开涉及包含一端结合E3泛素连接酶的Von Hppel-Lindau、cereblon配体的双功能化合物，另一端结合目标蛋白的部分，使得目标蛋白靠近泛素连接酶以实现目标蛋白的降解（和抑制）。本公开展示了与目标蛋白的降解/抑制相关的广泛药理活性。本公开的化合物和组合物用于治疗或预防由目标蛋白聚集或积累导致的疾病或紊乱。
